CURE 0F HERNIA BY MEANS OF INJECTIONSV.

Specification of Letters Patent No. 2,906, dated January 10, 1843.

To all whom t may concern:

Be it known that I, CHARLES T. SAGE, of the city, county, and State of New York, have invented a new and useful Improvement in Instruments for the Radical Cure of Reducible Hernia; and I dohereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making a part of this specication, in which- Figure l, is a side view; Fig. 2, a sectional drawing.

The nature of my invention consists in forming a syringe for the equal distribution of the irritant when used in producing inlainmation in the cure of hernia as follows. In a silver tube (a) is inclosed a glass one (b) the outer one having a slot cut in one side; on one edge of this slot, is marked an index, for a purpose hereafter described; the glass tube above named extends up about half the length of the outer one; from thence an inner metallic tube (c) occupies the space to the top; in the inside of this tube a coarse threadedscrew is Vcut (see section). Into the cylinder thus formed a piston (d) works just fitting the bore of the glass tube, when packed; the stem or piston rod has a collar just fitting the tube to steady it in its course; and on the side of the rod, a stud projects which works into t-he screw above named, theI bottom of the outside tube is closed, and in it is inserted a pipe This pipe is hollow nearly down to the end which is probe pointed. At the sides are three lateral holes just at the base of the solid end. A cap (f) can be added to the upper end of the. cylinder if desired.

In operating this machine the glass tube is filled with the liquid used for this purpose, as proposed by Dr. Anderson an incision is made down to the inguinal and femoral canal and the probe-formed point of the syringe is introduced and passed along the canal to the neck o-f the sack, the injectionv being made (by screwing in the vpiston as will readily he seen), along the hernial aperture, by means ofthe three openings in the sides of the probe, theliquid is spread properly over the whole surface. The index above named along the glass tube, enables the operator to inject the liquid in equal proportions along the whole aperture.

That I claim as my invention and desire to secure by Letters Patent isl. The combination of the glass tube (b) with the outside tube (a) having an indeX on it in the manner described.

2. I also claim the combination with the above the screw-tube (c) constructed and arranged in the manner and for the purpose set forth.

3. I further claim in combination with th syringe before specified the probe-shapedpoint constructed in the manner herein described.

CHARLES T.- SAGE.
